    Abstract: A planetary gear system including a first gear coupled to a shaft, a plurality of second gears in rotational engagement with the first gear, a fluid supply apparatus spaced apart from the second gears, and a carrier. The carrier includes an annular portion having a flow channel configured to receive a fluid deposited onto the carrier by the fluid supply apparatus. A pinion shaft is disposed through each of the second gears and includes a primary fluid conduit in fluid communication with the flow channel and at least one secondary fluid conduit in fluid communication with the primary fluid conduit. The primary fluid conduit and the at least one secondary fluid conduit facilitate a flow of the fluid from the flow channel to at least one bearing disposed on each of the pinion shafts and at least one thrust plate interposed between the second gears and the carrier.

    Abstract: A brushless direct current motor including a rotor, a first stator disposed adjacent the rotor, and a second stator disposed adjacent the rotor. The first stator is configured to selectively cause a rotational movement of the rotor during normal operation of the motor, and the second stator is configured to selectively maintain a stationary position of the rotor against a force exerted by an external source.

    Abstract: A tube yoke member and method of forming the tube yoke member. The method includes providing a tube blank and a mould having inner surfaces with a per- determined shape. The tube blank is then hydro-formed into a hydro-formed member with a pre-determined shape conforming to the inner surface of the mould. During the hydro-forming process, an amount of force is applied by a first and second actuator assembly attached to a first and second end portion of the tube blank. A first and second tube yoke member having a substantially tubular portion and a hydro-formed portion are then separated from the hydro-formed member. A first and second yoke arm opening is then formed in the first and second yoke arms of the first tube yoke member and a first and second yoke arm opening is then formed in the first and second yoke arms in the second tube yoke member.

    Abstract: A joint assembly (200) comprising a first joint member (232) that is drivingly connected to a second joint member (272) by one or more torque transfer elements (290). Drivingly connected to at least a portion of the second joint member (312) is a stub shaft (292). An end of the stub shaft, opposite the second joint member, is drivingly connected to at least a portion of a second shaft. At least a portion of a second end portion of a first shaft (202) is drivingly connected to at least a portion of a first end portion of the first joint member (232) and at least a portion of a first end portion of the first shaft has a gear member (210) with a plurality of gear teeth thereon.

    Abstract: A method of operating a final drive unit clutch. The method provides an electric motor coupled with a clutch. The electric motor including a stator, a first Hall-effect sensor coupled with the stator, a second Hall-effect sensor coupled with the stator, a third Hall-effect sensor coupled with the stator, and a rotor having at least one magnetic pole pair. The method also provides for a controller in electrical communication with the electric motor. The method includes determining a first ideal commutation point, and calculating a first offset of a first Hall-effect sensor state change from the ideal commutation point. The method further includes calculating a time delay of commutation, during the clutch transition between a non-torque transmitting position and a torque transmitting position, utilizing the first offset such that a second Hall- effect sensor state change corresponds with a second ideal commutation point.

    Abstract: A drive unit assembly. The drive unit includes a motor drivingly connected to a motor output shaft which in turn is drivingly connected to a sun gear of a gear assembly. The gear assembly further includes a gear assembly housing, one or more planetary gears and a pinion gear. At least a portion of the one or more planetary gears are drivingly connected to the sun gear, the gear assembly housing and a plurality of gear teeth circumferentially extending from an inner surface of a drive unit housing. The pinion gear has a first side and a second side, where the second side of the pinion gear is integrally connected to a first end portion of the gear assembly housing. Drivingly connected to the pinion gear is a differential ring gear of a differential assembly having a first side gear, a second side gear and one or more bevel gears.
